All the extracted Number objects will be treated as

Protected Member Functions
| ||Default constructor (necessary for the PortableObject interface). |
| ||Float64Sum (ValueExtractor::View vExtractor)|
| ||Construct a Float64Sum aggregator. |
virtual void ||init (bool fFinal)|
| ||Initialize the aggregation result.|
|fFinal ||true is passed if the aggregation process that is being initialized must produce a final aggregation result; this will only be false if a parallel approach is being used and the initial (partial) aggregation process is being initialized|
virtual void ||process (Object::View v, bool fFinal)|
| ||Incorporate one aggregatable value into the result.|
fFinal parameter is true, the given object is a partial result (returned by an individual parallel aggregator) that should be incorporated into the final result; otherwise, the object is a value extracted from an coherence::util::InvocableMap::Entry.
|vO ||the value to incorporate into the aggregated result |
|fFinal ||true to indicate that the given object is a partial result returned by a parallel aggregator|
